Yes, hence I never pursued it. "Although practicality beats purity" seems
to apply, but I don't care enough to push it.

Yes, that is true for all practical intent, if your installation has
extension modules. However, for a pure-python distribution, you need *no*
compilers installed. In that case, we still have a problem - at the moment,
the installation is guaranteed to fail for either Python 2.3 and before, or
for 2.4, depending on which CRTL was used to build wininst.exe.
To clarfify, I am talking about only how wininst.exe interacts with Python,
not extension building related issues (even though they are similar).
